Definitions
- This invention relates to electrical connectors. More particularly, it relates to electrical connectors having non-decoupling mechanisms.
- a dimple extends from the bottom of the spring and is adapted to engage ratchet teeth of different steepnesses to provide the non-decoupling function.
- this device has been found to have many drawbacks, particularly when it is needed to vary the coupling and decoupling torque of the connector.
- this connector is difficult to manufacture and positive contact between the ratchet valleys and the dimple is often difficult to maintain.
- an electrical connector including at least one cylindrical shell receiving an insert.
- the insert is adapted to receive at least one electrical contact.
- the shell includes a plurality of ratchet teeth which project circumferentially from the outer surface of the shell.
- a coupling nut is adapted to engage the cylindrical shell and a corresponding member matable with the cylindrical shell.
- a curved slot is provided on the inside of the coupling nut and receives and retains a spring sector therein.
- the spring sector includes a curved portion, which fits into the curved slot, and it further includes a spring finger bent inwardly from the curved portion having a free end engaging the ratchet teeth as the coupling nut is rotated.
- the spring finger and ratchet teeth arrangement provides for less torque as the free end is pulled across the ratchet teeth than when the free end is pushed across the ratchet teeth.
- FIG. 1 is a pictorial view of an electrical connector for which the subject invention is particularly useful
- FIG. 2 is an end view of the electrical connector of FIG. 1;
- FIG. 3 is a pictorial view of the coupling nut shown in FIG. 1;
- FIG. 4 is a side view of the connector body, in this case, a plug of the electrical connector of FIG. 1 showing the coupling nut removed;
- FIG. 5 is a pictorial view of a spring sector that is to be fitted into the slot in the coupling nut shown in FIG. 3;
- FIG. 6 is a partial front view of the other side of the electrical connector of FIG. 1 showing the spring sector-ratchet arrangement
- FIG. 7 is a cross sectional taken through section 7--7 of the connector shown in FIG. 6.
- FIG. 1 shows electrical connector 10, which includes cylindrical shell 12 and coupling nut 14.
- the cylindrical shell is a plug shell.
- Plug 12 is adapted to mate with a corresponding receptacle (not shown) or some other matable member.
- insert 16 which includes a plurality of holes 18, each adapted to receive an electrical contact.
- the insert is normally made of an electrically insulating material, such as a ceramic, plastic or rubber.
- the body of the shell 12 includes several longitudinal raised portions 20 which act as keys to be received in corresponding receptacle recessed keys so that the contacts are properly aligned.
- the coupling nut is mounted on a shoulder (not shown in FIG. 1) on the outer circumferential body of the shell 12 and includes threads 22 which are adapted to engage with corresponding threads on the plug which is to be mated to the receptacle.
- FIG. 2 shows the other end of the plug and coupling nut 10.
- the coupling nut includes the solid facing 24 and a pair of curved slots 26 and 28, which receive curved spring sectors 30 and 32, which are identical spring sectors and are shown better in the pictorial representation in FIG. 5. These slots 26 and 28, however, may be better seen in reference to FIG. 3, which is a pictorial view of the coupling nut.
- the barrel of the cylinder plug shell is adapted to be received in the circular hole 34 of the coupling nut.
- the slots 26 and 28 are curved and for receiving the curved spring sector shown in FIG. 5 by merely dropping the spring sectors into the slots.
- the spring sector is very easy to assemble with the coupling nut.
- FIG. 4 shows a side view of the cylindrical plug shell, over which rides the coupling nut 14.
- the inside of the front face 24 of the coupling nut abuts against the shoulder 36 of raised portion 38 which extends circumferentially about the barrel of the cylindrical plug, thus retaining the coupling nut in one axial direction.
- This raised annular portion 38 also forms ratchet teeth 40 over which rides the fingertip 42 of spring sector 30. The fingertip and the ratchet teeth cooperate with one another to provide the non-decoupling features as described herein, as particularly shown in FIGS. 5, 6 and 7.
- the curved spring sector 30 is fitted into slot 26 or 28 of coupling nut 14, and with the fingertip projecting down and onto the ratchet teeth 40, rides over the tops and into the valleys of the adjacent ratchet teeth.
- the steepness of the ramps on each ratchet tooth are different; that is, for example, ratchet tooth 44 includes a very steep ramp 48 and a less steep ramp 46. This feature will held enable the coupling nut to turn easier in one direction, that is, easier up the less steep ramp than the more steep one. The direction of turning across the less steep ramps is in the tightening direction of the coupling nut.
- the end advantage is taken of the differential in spring force created by pushing the finger up a ramp as opposed to pulling it across a ramp. This is because the spring compression is greater when one tries to compress the spring inwardly than when one tries to compress the spring upwardly.
- the spring and ratchet system described herein not only utilizes the differentials in steepnesses of the ramp of the ratchets, but also the spring pressure differentials in the spring sector itself.
- Axial shoulder 52 permits the finger top 42 to operate freely in the connector.
- Slit 43 provides a space between curved portion 45 and the finger tip, so that the spring tip would not tend to jam up in the coupling and decoupling modes.
- FIG. 7 is a cross-sectional view taken through section line 7--7 of FIG. 6.
- the body portion 54 of spring sector 30 is received in slot 26 of the coupling nut.
- the curved end portion of the body of the spring sector indicated at 56 will contact the curved portion 58 of the cylindrical shell.
- the finger 42 is received, in this embodiment, in a circumferential slot 60 in the coupling nut. As shown in FIG. 6, it is the ends of 62 and 64 of slot 26 that retain the spring sector in the circumferential direction.
- the end 50 of finger 42 engages ramp 48 of ratchet tooth 44.
- Washer 63 abuts against the end of the coupling nut, and permits it to rotate freely while retaining ring 66 rests in groove 68, and retains the washer, as well as the coupling nut itself from sliding off of the receptacle body. Washer 63 also retains the spring sector 30 from falling out of the slot 26 in the backward axial direction. Shoulder 70 retains the spring sector in the forward axial direction.
